Cloning
Would you ever like to see the pet you lost a long time ago, would you like to see a dinosaur? These things could be possible with cloning. Some of the positives of cloning are that if a pet or child or somebody else dies you could bring them back by cloning them. Another good thing about cloning is that we could clone organs so that if somebody needed a transplant there would be and organ available pretty quickly which would make the number of people that die while on the waiting list for one of the few organs available for transplant go way down and save lots of lives. One more thing cloning could do is bring back animals that are extinct, or make more that are almost extinct. This means that with cloning we could potentially see a dinosaur, or an early form of a human. Also species that are endangered or almost extinct could be copied lots of times to make enough of them for their species to survive longer than they would on their own.
